    The Highest Quality Contacts Out There. Period.

    When it comes to replacement contacts for Cutler-Hammer 6-45-2, the choice between Original Equipment Manufacturer (OEM) parts and aftermarket alternatives is crucial.

    Quality and Manufacturing Location
    OEM Contacts are produced by or for the original equipment manufacturer. While they guarantee a perfect fit and optimal performance, they often come with a higher price tag.

    We take pride in manufacturing our contacts in-house, in the USA. This allows us to closely monitor quality and ensure each product meets stringent standards.

    Material and Durability
    OEM Contacts are generally made from quality materials, but their exact composition and silver content can vary.
    Our Aftermarket Contact manufacturing process focuses on using high-quality copper and silver alloys, similar to the OEMs. Our extensive testing has proven that our contacts meet or exceed the OEM standards in terms of silver content, a key factor in conductivity and durability.

    Price and Value
    OEM Contacts are typically more expensive due to branding and the assurance of compatibility.

    Our Aftermarket Contacts offer a more cost-effective solution without compromising on quality. By controlling the manufacturing process, we provide a high-value product at a competitive price.
    Performance and Reliability
    OEM Contacts: Designed to offer reliable performance, but sometimes at a premium cost.

    Our in-house manufacturing and stringent testing ensure that our contacts perform on par with, or even surpass, OEM contacts in terms of reliability and longevity.

    Comparison with Competitors

    Many competitors source their aftermarket contacts from overseas, often resulting in inconsistent quality.

    Products from countries like China may not always meet the high standards required for industrial applications.

    Unlike our competitors, we manufacture our contacts in the USA, ensuring superior quality control. We avoid the pitfalls of inferior products often associated with overseas manufacturing.

    Test Reports and Standards Compliance
    One of the key aspects that set our aftermarket contacts apart is our commitment to transparency and quality assurance. We have conducted comprehensive test reports to validate that our silver content not only meets but frequently exceeds OEM standards. This is a testament to our dedication to providing products that are not just equivalent, but often superior to OEM parts.
